Heat the olive oil in a saucepan over medium heat.

Add the minced garlic and sauté for about 1 minute until fragrant.

Add the halved cherry tomatoes, salt, and black pepper to the saucepan.

Cook for about 10-15 minutes, stirring occasionally, until the tomatoes are soft and the sauce has thickened.

Stir in the balsamic vinegar if using, and cook for an additional 2 minutes.

Remove from heat and stir in the fresh basil just before serving.
